V Model is a popular Software development model.
It large number of resources to implement.

In v model every development stage will have corresponding 
testing stage.

Here test will be prepared in parallel with development 
phases.


i.e

After receiving  the business requirements are prepared 
then testing team will develop User acceptence Testcases.
But these testcases will be executed and the end of the 
project.

Here Business Requirements are very abstract in nature and 
it talks just about What user/customer actually needs.

System Requirement Specifications will be prepared From 
Business Requirements specifications.

SRS will be more elaborated then the Business requirements.
SRS tell what are system features need to be developped.

After seeing SRS Document Testing People will start 
preparing System Functional Testcases.

After receiving Highlevel Design Doc,Testing people will 
prepare the System Integration Testcases.

After seeing Low level Design doc,Development team willl  
will prepare the Component integration Testcases.

After coding development team will prepare uint testcases
and executes the unit test on the each individual unit or 
fnction.

Thus there is a mapping between the each development  phase 
with testing.
